<P>
<p>Computes summary statistics for a stream of n-tuples added using the
 <A HREF="../../../../../../org/apache/commons/math3/stat/descriptive/MultivariateSummaryStatistics.html#addValue(double[])"><CODE>addValue</CODE></A> method. The data values are not stored
 in memory, so this class can be used to compute statistics for very large
 n-tuple streams.</p>

 <p>The <A HREF="../../../../../../org/apache/commons/math3/stat/descriptive/StorelessUnivariateStatistic.html" title="interface in org.apache.commons.math3.stat.descriptive"><CODE>StorelessUnivariateStatistic</CODE></A> instances used to maintain
 summary state and compute statistics are configurable via setters.
 For example, the default implementation for the mean can be overridden by
 calling <A HREF="../../../../../../org/apache/commons/math3/stat/descriptive/MultivariateSummaryStatistics.html#setMeanImpl(org.apache.commons.math3.stat.descriptive.StorelessUnivariateStatistic[])"><CODE>setMeanImpl(StorelessUnivariateStatistic[])</CODE></A>. Actual
 parameters to these methods must implement the
 <A HREF="../../../../../../org/apache/commons/math3/stat/descriptive/StorelessUnivariateStatistic.html" title="interface in org.apache.commons.math3.stat.descriptive"><CODE>StorelessUnivariateStatistic</CODE></A> interface and configuration must be
 completed before <code>addValue</code> is called. No configuration is
 necessary to use the default, commons-math provided implementations.</p>

 <p>To compute statistics for a stream of n-tuples, construct a
 MultivariateStatistics instance with dimension n and then use
 <A HREF="../../../../../../org/apache/commons/math3/stat/descriptive/MultivariateSummaryStatistics.html#addValue(double[])"><CODE>addValue(double[])</CODE></A> to add n-tuples. The <code>getXxx</code>
 methods where Xxx is a statistic return an array of <code>double</code>
 values, where for <code>i = 0,...,n-1</code> the i<sup>th</sup> array element is the
 value of the given statistic for data range consisting of the i<sup>th</sup> element of
 each of the input n-tuples.  For example, if <code>addValue</code> is called
 with actual parameters {0, 1, 2}, then {3, 4, 5} and finally {6, 7, 8},
 <code>getSum</code> will return a three-element array with values
 {0+3+6, 1+4+7, 2+5+8}</p>

 <p>Note: This class is not thread-safe. Use
 <A HREF="../../../../../../org/apache/commons/math3/stat/descriptive/SynchronizedMultivariateSummaryStatistics.html" title="class in org.apache.commons.math3.stat.descriptive"><CODE>SynchronizedMultivariateSummaryStatistics</CODE></A> if concurrent access from multiple
 threads is required.</p>
